["Business Strategy and the Environment, EarlyView. ", "\nABSTRACT\nClimate change poses a growing managerial challenge for healthcare organizations. As climate risks transcend institutional boundaries, interorganizational connectivity is essential to harmonize standards and scale effective climate action. This study maps organizational responses aligned with SDG 13. Following the PRISMA protocol, a Scopus search (2015–2025) identified 129 eligible records. Thematic synthesis was combined with author‐keyword co‐occurrence and co‐citation analysis using VOSviewer and Biblioshiny (RStudio). The field is young but rapidly expanding after 2022. The following five thematic clusters emerge: (1) governance and system framing, (2) measurement and greenhouse‐gas accounting, (3) waste and impact management, (4) clinical operations decarbonization, and (5) planetary health and quality improvement. Governance and accounting practices catalyze climate action at the point of care, with progress strongest where measurement links to procurement and accountability. Research priorities include Scope‐3 supplier engagement, cost‐carbon evidence at service level, and a shift toward more connected, collaborative, and system‐oriented healthcare governance.\n"]
